The Obsidian Circle: The First Oath. The Obsidian Circle, #1

Some truths are not meant to be inherited. They are meant to be returned. For generations, the Ashcroft family has been tied to the Obsidian Circle-a secret organization built around an oath, an archive, and a truth powerful enough to survive the people who tried to control it. When Lucien Ashcroft returns to the mystery surrounding his family, he discovers that the Circle is not what history claims it was.
Hidden records, ancient keys, forgotten letters, and a buried door begin to connect his family to a secret that was never meant to belong to anyone. Beside him is Evelyn Hart, whose own memories hold a connection to the Circle that neither of them understands. As they follow the trail left by those who came before them, they uncover a history of power, secrecy, betrayal, and a promise known as the First Oath.
But the deeper they go, the more dangerous the truth becomes. The Circle was created to protect the truth. Somewhere along the way, it learned to possess it. Now Lucien must decide whether to inherit the Circle-or end what was never meant to survive. The Obsidian Circle: The First Oath is a psychological thriller of secrets, hidden histories, forbidden archives, and the dangerous cost of controlling the truth.
